Look Inside Programmable MEMS Clock Chips
A summary of the history of integrated circuits for clocking digital devices, following the trend toward the use of MEMS structures for resonators, with broad a description of how they are employed in chips from SiTime, Silicon Labs, IDT, and others. Article links to two sub-articles describing specifics of devices from two companies.
Test ANR Functionality On Your LTE Devices
As the first self-organizing network (SON) feature utilized in today’s LTE networks, automatic neighbor relation (ANR) is in high demand by network operators. With the planned progression of networks towards LTE-Advanced and heterogeneous networks, ANR is becoming more important, and so is testing the functionality on an LTE-capable, multi-mode wireless device.
IDEAS FOR DESIGN
Determine Equivalent ESR, Ripple Voltage, And Currents For Unequal Capacitors In Parallel
Capacitors are used in parallel to provide special performance attributes; however, it’s difficult to determine critical performance specifics of ESR, high-frequency ripple voltage, and individual RMS currents when they have unequal values. This numerical approach provides a straightforward solution to calculating the values based on published specifications.
Circuit Generates High-Frequency Sine/Cosine Waves From Square-Wave Input
Direct digital synthesis ICs can convert square waves to sine/cosine waves but their complexity is a disadvantage. This circuit uses simple CMOS logic and two switched-capacitor filters to perform the conversion.
